Abstract
A kind of anti-theft screw, including nut, small screw, locking cap and screw rod.Locking cap is fixed on the upper end of screw rod, is internally provided with internal thread and extends in screw rod.Small screw one end is fixed on nut, and the other end is screwed into the internal thread of locking cap and screw rod.Screw thread on small screw is identical with the thread rotary orientation on screw rod.The thickness of the locking cap is the half of small screw length.2 2.5 times of a diameter of screw diameter of the locking cap.The 1/4 1/5 of a diameter of screw diameter of small screw.The utility model is simple in construction, reasonable in design, by the suitable proportional sizes of each component, has reached the perfect adaptation of performance and cost;Screw is once screwed, and screw rod and locking cap can not just screwed out, so as to reach antitheft purpose, the part of anti-theft feature is needed available for car plate or other is fixed.
Description
Technical field
The utility model is related to a kind of screw, especially a kind of anti-theft screw.
Background technology
Anti-theft screw is also known as Anti-dismantle screw, and currently common screw, nut etc. uses a word, cross, hexagonal etc.
Regular texture is made, it is easy to arbitrarily turned by conventional tool, therefore does not possess anti-detaching theft-proof function, even if some minorities is non-
Demarcation screw processed, although such screw can prevent some conventional tools, as long as this kind of screw using Customization Tool also
Be can turn screw thread, do not have real antitheft effect.It is therefore desirable to design a kind of new Anti-dismantle screw, improve antitheft
Performance.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provide it is a kind of it is simple in construction, possess anti-detaching theft-proof function
Anti-theft screw.
To achieve the above object, the technical solution adopted in the utility model is:A kind of anti-theft screw, including nut, small spiral shell
Bar, locking cap and screw rod.Locking cap is fixed on the upper end of screw rod, is internally provided with internal thread and extends in screw rod.Small screw
One end is fixed on nut, and the other end is screwed into the internal thread of locking cap and screw rod.On screw thread and screw rod on small screw
Thread rotary orientation is identical.The thickness of the locking cap is the half of small screw length.A diameter of screw diameter of the locking cap
2-2.5 times.The 1/4-1/5 of a diameter of screw diameter of small screw.
It is preferred that, described nut top is provided with groove.
The utility model is simple in construction, reasonable in design, by the suitable proportional sizes of each component, has reached performance and cost
Perfect adaptation;Screw is once screwed, and screw rod and locking cap can not just screwed out, so that antitheft purpose has been reached, can
The part of anti-theft feature is needed for fixing car plate or other.
Brief description of the drawings
Fig. 1 is the structural representation after the utility model assembling.
Fig. 2 is the structural representation after small screw and the separation of big screw rod.
In figure:1- nuts;2- small screws;3- locking caps;4- screw rods;5- grooves.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly, it is fully described by, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
As depicted in figs. 1 and 2:A kind of anti-theft screw, for fixed car licence plate, including nut 1, small screw 2, locking cap
3 and screw rod 4.Locking cap 3 is fixed on the upper end of screw rod 4, is internally provided with internal thread and extends in screw rod 4.The one end of small screw 2
It is fixed on nut 1, the other end is screwed into the internal thread of locking cap 3 and screw rod 4.On screw thread and screw rod 4 on small screw 2
Thread rotary orientation is identical.The thickness of the locking cap 3 is the half of the length of small screw 4, a diameter of screw diameter of the locking cap
2-2.5 times, the 1/4-1/5 of a diameter of screw diameter of small screw, these parameters be limited to guarantee cost while, can carry
For enough screwing forces and the fixed force enough to licence plate.The described top of nut 1 is provided with groove 5.
In use, screw rod, which is inserted into, to be needed to fix in the screw of car plate, then small screw is screwed into locking cap and tightened,
When nut is backed out, locking cap and screw rod will not be loosened, so as to serve antitheft purpose.
